dc.descriptionWe present a detailed study of the Higgs sector within an extension of the Minimal Supersymmetric Standard Model that includes one Complex Higgs Triplet (MSSM+1CHT). The model spectrum includes three singly charged Higgs bosons as well as three CP-even (or scalar) and two CP-odd (or pseudoscalar) neutral Higgs bosons. We present an approximated calculation of the one-loop radiative corrections to the neutral CP-even Higgs masses ($m_{H_i^0}$) and the couplings $H_i^0 Z^0 Z^0$ ($i=1$, 2, 3), which determine the magnitude of the Higgs-strahlung processes $e^+ e^-\to Z^0 H^0_i$. Limits from LEP2 are then considered, in order to obtain bounds on the neutral Higgs sector. Further, we also include the experimental limits from LEP2 on $e^+e^-\to H^+H^-$ and those on BR($t \to b H^+$) from Tevatron, to derive bounds on the mass of the two lightest charged Higgs bosons ($H_1^{\pm}$ and $H_2^{\pm}$). Concerning the latter, we find some cases, where $m_{H_1^{\pm}} \simeq 90$ GeV, that are not excluded by any experimental bound, even for large values of $\tanβ$, so that they should be looked for at the Large Hadron Collider (LHC).
